Margaret Stewart associated this cairn with other upland cairns in Perthshire e.g. Strathgroy and even suggested it had a peristalth . Can’t see the resemblance myself , the others are much bigger and in the case of Strathgroy the peristalth is obvious . Nothing like it here .
just looked this up
PERISTALITH : a ring of upright stones around a mound or dolmen
cheers
Glad I wasn't the only person that had to look up what a peristalith was :)
